Hi
I'm new on arduino and raspberrypi world and need some help with this.
I have this configuration:
-RaspberryPI 2
-Raspbian
-Configuration of Ardulink into raspberry LINK
-Arduino software installed into raspberry
-This is a code compiled and launched from raspberrypi
#include <eHealth.h>
// The setup routine runs once when you press reset:
void setup() {
Serial.begin(115200);
}
// The loop routine runs over and over again forever:
void loop() {
float ECG = eHealth.getECG();
Serial.print("ECG value : ");
Serial.print(ECG, 2);
Serial.print(" V");
Serial.println("");
delay(1); // wait for a millisecond
}
And this is java class wich uses Ardulink
import org.zu.ardulink.Link;
import org.zu.ardulink.RawDataListener;
import org.zu.ardulink.event.ConnectionEvent;
import org.zu.ardulink.event.ConnectionListener;
import org.zu.ardulink.event.DigitalReadChangeEvent;
import org.zu.ardulink.event.DigitalReadChangeListener;
import org.zu.ardulink.event.DisconnectionEvent;
public class Main {
private final static String COMPORT = "/dev/ttyS80";
private final static int BAUDRATE = 115200;
private static Link link;
public static void main(String[] args) {
System.out.println("Conecting...");
connect();
}
public static void connect(){
link = Link.getDefaultInstance();
link.addConnectionListener(new ConnectionListener() {
@Override
public void disconnected(DisconnectionEvent e) {
System.out.println("Error connect");
}
@Override
public void connected(ConnectionEvent e) {
System.out.println("Connect succesful");
try {
System.out.println("Wait...");
Thread.sleep(2000);
System.out.println("Done!");
} catch (InterruptedException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
}
});
link.connect(COMPORT, BAUDRATE);
startListenStatus();
}
public static void startListenStatus(){
link.addDigitalReadChangeListener(new DigitalReadChangeListener() {
@Override
public void stateChanged(DigitalReadChangeEvent e) {
// do something
System.out.println("STATECHANGED: " + e.getIncomingMessage());
}
@Override
public int getPinListening() {
return 11;
}
});
link.addRawDataListener(new RawDataListener() {
@Override
public void parseInput(String id, int numBytes, int[] message) {
System.out.println("ParseInput: ");
StringBuilder build = new StringBuilder(numBytes + 1);
for (int i = 0; i < numBytes; i++) {
build.append((char) message[i]);
}
String msgString = build.toString();
if (msgString.startsWith("SERIAL")) {
msgString = msgString.substring("SERIAL".length());
// print data to console
System.out.println(msgString);
int dataNewPoint = Integer.parseInt(msgString);
// add new data point to the real time chart
}
}
});
}
}
Sensor eHealth is connect to arduino and arduino is connected to raspberrypi through usb cable.
The problem is that I not get any messages in console when launch java program.
Thanks for all
